Title: Direct extraction of high oil content seeds - partially extracted mash being soaked in solvent and disintegrated without fire risk
Inventor: KEHSE WOLFGANG DR ING
IPC: C11B1/10
Filed: 1973-09-13
Abstract: Seeds having a high oil content are extracted directly in two solid/fluid operations. The bruised grain leaving the first extraction process wet with the organic solvent, and having a residual oil content of 8-20wt. %, is wet-ground with or without the addn. of partly satd. solvent. The process is carried out continuously until the cell walls of the grain are thoroughly disintegrated before the mash goes to final extraction, and is effected pref. in a multi-stage tube mill with an unbalance drive. A hydrocyclone separates the sufficiently ground matl. after the first pass so that only the coarser constituents go on for further milling. Method eliminates the necessity for the removal of the solvent before the cell-wall disintegration, facilities extraction and reduces steeping time.

Title: Binary coded video signal compression method - with analogue signals sampled quantised and coded into words of length N
Inventor: WENDT HARTMUT DIPL ING
IPC: H04N19/59
Filed: 1974-01-19
Abstract: Codewords are transmitted and reconverted in the receiver in luminance signals. Adjacent scanned values are compared at the transmitter, and the richness of picture details determined and a criterion derived. Depending on this criterion, a first scanning frequency and a coarse quantisation are used, so that at least two adjacent scanned values are transmitted in one codeword. Picture parts with few details are scanned at a second frequency, and a very fine quantisation is used, so that only one scanned value and one code signal derived from the criterion can be transmitted in one codeword. When the code signal is missing, the two coarsely quantised scanned values are reconverted by the first frequency, and when the code signal is present, the finely quantised scanned value is reconverted by the second frequency.

IPC: C23C18/16
Filed: 1974-03-30
Abstract: Chemical and/or electrochemical deposition of metals onto substrates immersed in a bath which is subjected either before or during deposition to a "deposing" treatment to prevent porosity in the metal deposited. Prior to and/or during deposition, the bath is thermodynamically de-gassed and thereby "depored".
